Beardtongue - Large-Flowered (Penstemon grandiflorus)
Large-flowered Beardtongue prefers full sun to partial shade, dry mesic to dry conditions, and poor soil containing rocky material or sand. When mature it can reach heights of 2'. Its stunning large, tubular pink to purple flowers bloom for just a few weeks in May or June.
This plant is endangered in some states and is typically rare to see in the wild. Bumblebees like to visit the flowers for nectar and this plant is well liked by birds. In addition to the many pollinators it attracts, Penstemon grandiflorus is one of the host plants for the Chalcedon Checkerspot and Edith's Checkerspot within the western region of its range.
